public interface IlvChartServerAction
extends EventListener

The IlvChartServerAction interface should be implemented by objects that need to be notified of named actions requested from the client. The client queries the server for a new image with additional parameters appended to the request (in the form &action=actionName(arg1,arg2,...)), so that an action such as adding, removing, or highlighting data points can be performed before the image is generated. You create an action on the server side by implementing this interface and registering your implementation by calling the IlvChartServletSupport.addServerAction(java.lang.String, ilog.views.chart.servlet.IlvChartServerAction) method. An IlvChartServerAction can be executed either in the request thread, or in the swing event dispatch thread, depending on the value returned by getExecutionThread().
